True or False: Cells in most tissues have only hexokinase for energy metabolism. Liver cells also have glucokinase that is used for taking up glucose for glycogen synthesis. Hexokinase has a higher Km for glucose than glucokinase.


True or False: Some vitamins, such as thiamine, play a major role in enzyme’s catalytic function. In fact, some are parts of the protein and are called prosthetic groups of the enzyme.


True or False: The substrate binding site in an enzyme is like a pocket; it discriminates specific substrate from other compounds primarily by size. Only the ones small enough to get in get reacted.

A low KM means high affinity and vice versa a high KM means low affinity. F. The question is kind of incomplete. Undecided hm...

T - Many vitamins are prosthetic groups. Proteins with lipid, carbohydrate, and nucleic acid prosthetic groups are called lipoproteins, glycoproteins, and nucleoproteins, respectively.

F - Some substrates are inhibitors, and so they prevent reactions from taking place.
